Yeah, they did a great job on the lens, whatever they did!
As far as colour, I'm the same way for the most part. Whatever is cheap. I still have some of the Agfa I got from Irv, and need to use it up as it's long expired now...
I just wish the colour film makers would just settle down and stop all this crazy lomo-esque colour shifting nonsense they do.
I'm just an old stick I guess, but a few good colour selections that are consistent would suit me fine. And keep the price affordable.
Okay, I'm off my little ranty soap box.
Back to the Ultra Wide and slim, my original still works that I bought for seven dollars new in a box when they first hit the pavement. it looks like a train wreck, but that lens, as you said...it's a keeper.
